Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for suppressing embrittlement for improving solvent barrier characteristics of plastic materials, especially membranes by surface fluorination treatment. SOLUTION: An antioxidant such as nitric oxide (NO), dinitrogen dioxide (N2O2), nitrogen dioxide (NO2), dinitrogen trioxide trioxide (N2O3), dinitrogen tetraoxide (N2O4), sulfur dioxide (SO2), sulfur trioxide (SO3), an amine having 1-4C hydrocarbon group, phosphine, a phosphine derivative or a trialkyl-monochlorosilane is used as an agent for suppressing embrittlement for surface-fluorinated plastic materials.
